AUTOMATIC STATION S'IGNAIJ DEVICE.

Application filed may Referring to the drawing forming a ma-' terial part ofthis disclosure:

1 is constructed according to this invention.

Fig- 2 is at front view thereof seen from within. the casing.v I r Fig. 3is a sectional view taken on the line 3-3 of Fig. 2; p o I Fig, 4 is a sectional view taken onv the line 44 of Fig. 2.

Fig. 5 is p a sectional view taken on. the line 55 of Fig. 2.. v

Fig. 6 is a schematic wiring diagram of thedevice. Y

Fig. 7- is ,an enlarged fragmentary view of a portion of Fig. 4. 7 I I The reference numeral 10 indicates gen erally a casing having a top cover11, and a'window 12 on one side, and another win.- d'ow; 13 in the other side 9f the casing. A strip of material 14 is formed along its edges with apertures 15, and has printed on its outer surface two consecutive lists of stations in consecutive order, indicated roughly 40 by the names of stations 16 and so spaced that the same station names appear simultaneously at the windows 12 and 13. Several rollers 17 suitably mounted within the casing guides the strip of material 14.

electric motor 18 having on its shaft a pinion 19, which meshes witha large gear 20 having a small gear 21 coaxially mounted. This small gear 21 meshes with a broad gear 22 meshing with a narrow gear 23 slidably mounted on a shaft grooved collar. 25 engaged by a fork 26 which is pivoted at 27 and connected to a lever 28 projecting through a slot 29 in casing 10. Mounted on opposite sides of the gear 23 are other gears 30, 31 in different rand-oi" the objects and" advantages a perspective view of a device- Suitably mounted within the casing is an 24, and having a 1327, Serial No. 190,612..

planes, as .showngin Fig. '5, so that gear 23 meshes with either gear or 31, depend-- ing on the position of lever28. The gear 30 connects with a roller 32 capable of driving the strip 14, while gear 31 connects with another roller 33 also capable of driving the strip 14; 'lVhen gears 31 mesh the strip 141;; driven in one direction while when gears 30 1nesh the strip is driven in the other d rection, so as to correctly display the station: irrespective of the direction' in which a train may'run having the invention device. I j v Suitably mounted in the casing 1.0 isi a roller '34 having teeth 35 engaging, in the apertin es 15-of strip14, and this idler is formed witl'i a pair of diametrically opposite slots 36 engageable by a tongue 37 slidably mounted and! controlled by a solenoid I 38 so that when current flows in the sol enoid, the member 37 1s disengaged from the slot 36 permitting the strip 14 to advance. and

, the current is automatically cut off, hereafter explained, to permit the member 3? to engage the next slot 35,-tl1usal lowi-ng- 1/ rotation each time, of roller 34, and allowing a certain amount of advancement of the strip The rollers 32, 3 3slip; against the strip 14 when the strip is locked by the idler 34.

Projecting from the roller 34 is a pin 39 engaged in a slot 40 formed by the side of make and breaklever 411 and arrod 42 slidable in grooves 43v in projections; 44. from the lever 41.: Gain arms 45 act againstthe rod 42, and are connected with lock pinions :46 engaged by pawls 47 urged into engagement by springs 48, while other springs 49 normally urge the rod 42 against the cam arms 45 by acting between the rod 42 andthe projections 44. It should be understood that the movement of the make and break lever 41 may be predetermined by adjusting the width of the slot between the edge thereof and the edge of the adjustable bar 42. hen the slot is increased in width by setting of the pawl 47 soas to position cam 45 at an angle to the bar 42 the movement of the lever 11 for each'half revolution of the roller 34 is decreased.

The make and break lever 41 is pivoted at 50 and has its other arm 51 formed with a contact 52 engageable with a stationary contact-53 when 37 engages one of the slots 36, or. with a contact 54 when 37 engages the other of the slots 36.

One lead of motor 18 connects to bat teries 56 thereafter to the handle contactof the two way switch 57. Contact 58 of the to have 23 engage 30 or 31 as desired. The

motor-man engageshandle 62 of switch 57 against the contact 59. A current then lows from the battery 56 to handle contact of the switch 57, to 5.), 53, 52, 50, (50, through solenoid 38, switch 61, which must be closed, and the motor 18, back to battery 56. The energized solenoid movesv 87 free from slot 36. Motor 18, through the chain of gears,

drives the strip 14, which also moves the roller 34, andpin 39 moves make and break 41. When the pin 39 reaches the diametrically opposite side of its original position, contacts 52 and 53 break, while 52 and 54 make. Immediately solenoid 38 allows 37 to engage a slot 36 holding the strip 14 in its new position, while the motor 18 comes to a stop. At the next station, the motor-man throws 62 onto 58. A complete circuit then exists between the battery 56, the switch 57, contact 58, contacts 54, 52, 50, 60, 38, 61, 18, and back to 56. A repetition of that just before explained occurs, and this may be continued for each station.

The direction of travel of ribbon 14 may be automatically reversed by providing lever 28 with an arm 28, and providing the ribbon 14 with a trip bar 14 adapted to move the arm 28 at a certain position of the ribbon so as to shift the gears as may be manually shifted by operating lever 28.

While I have illustrated and described my invention with some degree of particularity, I realize that in practice various alterations therein may be made. I therefore reserve the right and privilege of changing the form of the details of construction or otherwise altering the arrangement of the correlated parts without departing from the spirit or the scope of the appended claims.

Havin thus described 111 invention what O y 3 I claim as new and desire to secure by United States Letters Patent is V 1. In a device of the class described, the combination with a roller provided "with means for gripping a printed strip, and having a pro ecting pm, of a make and break mounted on said rollers, a motor drivenv means for moving the strip towards the front or rear of the casing, gripping the strip, a solenoid operable tongue normally engaging the control roller for locking it against rotation, a pin ex tending from the said control roller, a make and break operable by the pin upon rotation of the control roller, a power circuit including the said motor, the said solenoid, the said make and break, and a two pole switch for energizing the motor and solenoid upon engaging the switch on one pole, to free the control roller and to advance the strip until the circuit is broken by the make and break, and upon engaging the switch on the other pole, to repeat the operation;

In testimony whereof I have aflixed my signature. 1
